第一步：
//在info.plist中添加一個字段：view controller -base status bar 設置為NO；
//導航顏色
[[UINavigationBar appearance] setBarTintColor:[UIColor XXXX]];
[[UITableViewCell appearance] setBackgroundColor:[UIColor XXXX]];
//設置狀態欄（信號區）白色
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
//默認帶有一定透明效果，可以使用以下方法去除系統效果
[navigationController.navigationBar setTranslucent:NO];
//更改導航標題字體大小與顏色要在第一級頁面設置 如下
// 設置導航默認標題的顏色及字體大小
self.navigationController.navigationBar.titleTextAttributes = @{UITextAttributeTextColor: [UIColor whiteColor], UITextAttributeFont:[UIFont boldSystemFontOfSize:18]};
第二步：
//UIImageRenderingModeAlwaysOriginal 讓圖片表現的模式為圖片的原始樣式 用於去掉系統添加的顏色
if ([[UIDevice currentDevice] systemVersion].floatValue >= 8.0) {
self.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"title" image:[[UIImage imageNamed:@"Image.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] selectedImage:[[UIImage imageNamed:@"ImageS.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
}else{
self.tabBarController.tabBarItem.title = @"title";
if ([[UIDevice currentDevice] systemVersion].floatValue >= 7.0) {
[self.tabBarController.tabBarItem setFinishedSelectedImage:[[UIImage imageNamed:@"Image.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] withFinishedUnselectedImage:[[UIImage imageNamed:@"ImageS.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
}else{
[self.tabBarController.tabBarItem setFinishedSelectedImage:[UIImage imageNamed:@"Image.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"ImageS.png"]];
}
}
//tabbar顏色 用於更改字體顏色
[self.tabBarController.tabBar setTintColor:[UIColor XXXX]];
